Tobias, the other Animorphs, and Ax have seen things so bizarre that no sane person would believe their story. No one would believe that aliens have taken over Earth, and are in the process of infesting as many humans as possible. No one could believe the battles and missions and losses these six kids have had to deal with. And its not over yet.Tobias has been captured by the same human-Controller that nearly tortured him to death once before. She claims that shes now a part of the Yeerk Peace Movement. That she just needs a favor. Tobias isnt sure what to believe, but he knows that if the Animorphs and Ax dont find him soon, what he believes wont matter anymore...
